Expression of mmp Genes and Their Inhibitors Is Altered in hand2 Mutants

(A) Comparison of mmp and timp expression in wild-type and han^s40-/- samples by quantitative real-time PCR (two independent experiments, three replicates of wild-type and han^s40-/- samples each time). The results are represented as relative expression levels that are normalized to β-actin (mean ± SEM).

(B) Proportion (mean ± SEM) of wild-type embryos (n = 29), wild-type embryos injected with 0.5 ng of mmp14a MO (n = 44), han^c99 heterozygotes (n = 55), and han^c99 heterozygotes injected with 0.5 ng of mmp14a MO (n = 70) showing gut-looping phenotypes according to foxa3 expression. Three independent experiments were conducted.

(A and B) Asterisks indicate statistical significance: *p < 0.05; **p < 0.01.

(C) Diagram of Hand2 regulating asymmetric LPM migration during zebrafish gut-looping morphogenesis. See also Figure S4.
